The Dynamic Equation of Motion of Driving Mechanism of a Freight Elevator

Goal of the analysis of dynamics of a freight elevator is to find out, what acceleration will the lift be moving with. Value of the acceleration was found out with using system reduction method. Movement of the system was reduced to movement of elevator's cabin. The elevator's mechanism can be considered as planar mechanism with one degree of freedom in vertical direction. The third part of the document deals with applying the reduction method on a specific mechanism of freight elevator. Conclusion of the document contains analysis of the results, how do singular parameters affect the result and suggests ways, which the results could be verified in, or how to reach requested value and characteristics of the acceleration.
